How This Combo Ranks

The AMD Ryzen 7 3700X paired with the AMD Radeon RX 7700 lands at rank 1324 out of 2996 tested combinations in Microsoft Flight Simulator. This places the combo in the 44th percentile of all tested systems, meaning roughly 56% of configurations deliver higher average frame rates in this specific title. The ranking reflects a mid-pack position that is respectable given the component mix, but it is not a top-tier pairing for a simulator known for its demanding rendering of vast landscapes and dense urban environments.

Benchmark results indicate the combo is firmly positioned in the upper-middle tier of the database. The CPU's average benchmark score of 34260 places it in the 84th percentile against all processors, while the GPU's average score of 15852 lands in the 58th percentile against all graphics cards. This asymmetry is telling: the processor is a stronger relative performer than the graphics card, which shapes how the system behaves under different settings and resolutions in Flight Simulator. The data suggests the CPU has headroom to drive higher frame rates if the GPU were more capable, but at 4K Ultra the pairing reaches its practical limit.

The nearest rivals for the CPU show how tightly clustered this processor is with modern alternatives. The AMD Ryzen AI 7 350 scores 34222, just 0.1% lower, and the AMD EPYC 4244P matches at 34220, also 0.1% lower. The Intel Core i5-13450HX edges ahead at 34333, a 0.2% margin, while the Intel Core Ultra 7 165H trails at 34083, 0.5% behind. These deltas are negligible in real-world gaming, confirming the 3700X remains competitive in compute-heavy workloads despite being an older Zen 2 design.

For the GPU, the rival picture is equally tight. The AMD Radeon R9 370X scores 15862, a 0.1% advantage over the RX 7700. The AMD Radeon RX 9060 leads by 1% at 16014, while the AMD Radeon Pro W5500 sits 1.1% behind at 15679. The NVIDIA GeForce RTX 3060 Ti posts 16129, which is 1.7% higher. None of these differences translate into meaningful frame rate gaps in Flight Simulator, where the rendering engine's behavior often matters more than raw compute scores.

GPU Role

The AMD Radeon RX 7700 brings 16 GB of GDDR6 memory on a 256-bit bus, delivering 624.1 GB/s of bandwidth. This is a substantial memory allocation for a flight simulator that streams terrain, weather, and airport detail continuously. The 16 GB capacity ensures the card does not hit a VRAM ceiling at any tested resolution, even at 4K Ultra where texture density is highest. The memory clock runs at 2438 MHz, which translates to 19.5 Gbps effective, and this bandwidth proves sufficient to feed the 2560 shading units without causing stutter in the measured data.

The GPU's clock behavior matters for understanding the FPS results. The base clock is 1900 MHz, the game clock is 2041 MHz, and the boost clock reaches 2459 MHz. In Flight Simulator, the card operates closer to its game clock under sustained load, which is typical for a rendering workload with heavy draw calls. The boost clock provides headroom for lighter scenes, such as high-altitude cruising over sparse terrain, but the measured average FPS suggests sustained performance aligns more with the game clock than the peak boost.

The RX 7700's architecture is RDNA 3.0 on a 5 nm process, with 28,100 million transistors on a 346 mm² die. It offers 40 ray tracing cores and 96 ROPs, with a pixel rate of 236.1 GPixel/s and a texture rate of 393.4 GTexel/s. For Flight Simulator, which does not heavily rely on ray tracing in its default rendering path, the rasterization throughput is the primary driver of the measured FPS. The FP32 compute of 25.18 TFLOPS provides ample headroom for the simulation's physics and weather calculations that run on the GPU.

The GPU's 58th percentile ranking against all graphics cards is the bottleneck in this pairing. At 1080p Low, the combo reaches 126 FPS, which is high, but the CPU is not fully taxed at that setting. As resolution increases, the GPU becomes the limiting factor, which is evident in the FPS scaling from 1080p to 4K. The card's PassMark G3D score of 20974 and 3DMark Steel Nomad DX12 score of 2865 place it in a competitive range, but not at the top echelon required for 4K Ultra at high frame rates in this simulator.

Resolution Scaling

The measured FPS data reveals a clear pattern of GPU-bound scaling as resolution increases. At 1080p High, the combo averages 74 FPS. Moving to 1440p High drops this to 60 FPS, a 19% reduction. At 4K High, the average falls to 44 FPS, which is 41% lower than the 1080p High result. This scaling curve is steeper than what a CPU-bound system would show, confirming that the RX 7700 is the limiting component at higher resolutions.

The Low settings tell the same story with higher absolute numbers. At 1080p Low, the combo hits 126 FPS. At 1440p Low, it drops to 102 FPS, a 19% decline. At 4K Low, the average is 75 FPS, which is 40% lower than the 1080p Low figure. The consistency of these percentage drops across settings indicates a stable GPU bottleneck that scales predictably with pixel count.

Medium settings provide the only data with min and max FPS values, offering insight into frame pacing. At 1080p Medium, the average is 98 FPS with a min of 84 and max of 113. At 1440p Medium, the average drops to 79 FPS with a min of 67 and max of 91. At 4K Medium, the average is 59 FPS with a min of 50 and max of 67. The spread between min and max is roughly 30% at each resolution, suggesting occasional dips during complex scenes such as airport approaches or city flyovers.

The Ultra settings show the heaviest load. At 1080p Ultra, the average is 70 FPS. At 1440p Ultra, it drops to 57 FPS, an 18.6% reduction. At 4K Ultra, the average falls to 42 FPS, which is 40% lower than the 1080p Ultra result. This 42 FPS average at 4K Ultra is below the 60 FPS threshold many users consider smooth for a simulator, indicating the combo is best suited for 1080p or 1440p gaming with high settings.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings average 126 FPS, which is the peak performance in the entire measured dataset. Medium settings average 98 FPS with a min of 84 and max of 113. High settings average 74 FPS. Ultra settings average 70 FPS. The spread from Low to Ultra is 56 FPS, indicating that settings have a significant impact at this resolution, but all settings remain playable.

At 2560x1440, the performance drops consistently. Low settings average 102 FPS, a 19% reduction from 1080p Low. Medium settings average 79 FPS with a min of 67 and max of 91. High settings average 60 FPS, which is exactly at the 60 FPS threshold. Ultra settings average 57 FPS, dipping below the smoothness threshold. The drop from Low to Ultra is 45 FPS, a slightly smaller range than at 1080p due to the GPU becoming more constrained.

At 3840x2160, the GPU is clearly the limiting factor. Low settings average 75 FPS, which is still playable but 40% below the 1080p Low result. Medium settings average 59 FPS with a min of 50 and max of 67. High settings average 44 FPS. Ultra settings average 42 FPS. The drop from Low to Ultra is 33 FPS, the smallest range across resolutions because the GPU is saturated even at Low settings. The 4K Ultra average of 42 FPS is the lowest measured result in the entire dataset.

The Medium settings data provides the only min/max values, which show consistent frame pacing at each resolution. At 1080p, the min is 84 FPS and max is 113 FPS, a 29 FPS spread. At 1440p, the min is 67 FPS and max is 91 FPS, a 24 FPS spread. At 4K, the min is 50 FPS and max is 67 FPS, a 17 FPS spread. The narrowing spread at higher resolutions suggests the GPU's consistent load reduces frame time variance, even as average FPS declines.

CPU Role

The AMD Ryzen 7 3700X provides 8 cores and 16 threads, running at a base clock of 3.60 GHz and a boost clock of 4.40 GHz. This is a Zen 2 architecture processor on a 7 nm process, with 3,800 million transistors on a 74 mm² die. The 32 MB L3 cache and 51.2 GB/s memory bandwidth on a dual-channel DDR4 interface are sufficient for Flight Simulator's simulation logic, which relies on single-thread performance for flight dynamics and multi-thread performance for terrain loading and AI traffic.

The CPU's benchmark results show a strong multi-threaded profile. The Cinebench R15 multi-core score is 2092, while the single-core score is 204. The Geekbench multi-core score is 8899 with a single-core score of 1593. The PassMark multithread score is 22458, and the PassMark single-thread score is 2656. The PassMark physics score of 1181 and floating point math score of 39005 indicate solid compute capability for the simulation's physics calculations.

In Flight Simulator, the CPU's role is to feed the GPU with draw calls and handle the game's background simulation threads. The 84th percentile ranking against all CPUs suggests this processor is not a limiting factor at 1080p Low, where the combo achieves 126 FPS. However, the benchmark results indicate that the CPU's single-thread performance, while respectable, is not exceptional. The PassMark single-thread score of 2656 is modest compared to modern processors, which may cause slight frame rate dips in CPU-heavy scenes such as dense city approaches.

The CPU's nearest rivals show how close the 3700X remains to newer parts. The AMD Ryzen AI 7 350 and AMD EPYC 4244P are within 0.1% of the 3700X's average score, while the Intel Core i5-13450HX is 0.2% faster. This clustering indicates that the 3700X's 8-core/16-thread configuration is still competitive for gaming workloads, even if newer architectures offer better efficiency. The processor's 65 W TDP and unlocked multiplier allow for overclocking headroom, but the measured FPS data does not indicate whether the tested configuration used any overclock.

The CPU's memory support for DDR4 at dual-channel bandwidth of 51.2 GB/s is adequate for Flight Simulator's data streaming needs. The 32 MB L3 cache helps with terrain data reuse, reducing the need to fetch from system memory. The PCIe Gen 4 support with 24 lanes provides ample bandwidth for the RX 7700's PCIe 4.0 x16 interface, ensuring no bottleneck in data transfer between CPU and GPU. In this pairing, the CPU is the stronger component, and the data shows the GPU becomes the limiting factor as resolution and settings increase.
